What Does Brief Loss of Consciousness Indicate.. is it a Sign of Stroke?

If you have had episodes of brief loss of consciousness then you may have had Transient Ischemic Attack (TIA). Transient Ischemic Attack or TIA is temporary and caused by transient loss of blood supply or oxygenation of brain.
Transient Ischemic Attack or TIA does not cause permanent minor or major damage. Alternative cause may be Acute Ischemic Stroke. If you have been experiencing brief loss of consciousness then you should see neurologist for investigation and preventive treatment within 2 to 7 days if not earlier.1

What Can Cause Brief Loss of Consciousness?

First of all, if you have lost consciousness for brief period you should see your primary care physician or visit ER as soon as possible. There are several causes for brief loss of consciousness like transient ischemic attack, low blood pressure, shock, hypoxia, seizures, heart diseases (heart stroke), arrhythmia, hypoglycemia (low blood sugar) anemia, side effects of medications, concussion, dehydration and sleep deprivation.

Is On and Often Headache Related to Brief Period of Unconsciousness?

Yes, you may get headache for few hours after brief loss of consciousness if you had transient ischemic attack (TIA). If you are suffering with headache lasting 4 days and more after loss of consciousness you may have had an acute ischemic stroke (AIS).

If you ignore the symptoms of brief loss of consciousness then you could be heading for an attack of Acute Ischemic Stroke. 33% of patients after transient ischemic attack end up in ischemic stroke some time within 1 year, if preventive measures are not taken. Early diagnosis and MRI2 studies do help to find the cause of brief loss of consciousness.
